Engraving by Alfred Jones after Captain Seth Eastman, US Army. A trophy scalp was believed to impart the powers of the scalped enemy on the owner. Scalping was formerly a custom in Europe and Asia, and not all Native American tribes practiced it. European colonists took scalps and heads themselves, and offered bounties for scalps which led to an escalation of intertribal warfare and more scalping. Illustration from 'Information respecting the history, condition and prospects of the Indian tribes of the United States. Part 2' by Henry Rowe Schoolcraft (1793-1864), published in Philadelphia in 1847.
